DEVICE FOR EJ'EGTING PASTE AND Application filed June 4,

To all whom it may concern:

Be it known that I, JoHN A. ERIKSSON, a citizen of the United States, residing at Bloomfield, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Devices forEjecting Paste and Cream from Collapsible Tubes, of which the followin is a specification.

This invention re ates to a device for ejecting paste, cream and analogous substances from collapsible tubes, and the general object of the same is to provide a simple and effective attachment that may be readily applied to a ledge or any suitable support in a position for ready accessibility and to which a collapsible tube may be easily applied and effectively compressed or collapsed to expel. the contents thereof when desired for use.

A further object of the invention is to provide a device of the class specified to which the lower end of a collapsible or compressible tube may be easily applied and which will operate to regularly roll the compressed part of the tube and evenly force the contents of the rolled portion into that part of the tube which is left unrolled, and.

thus discharge from he outlet of the tube: such quantities of the paste or cream as may be desired for use, and eventually'fully and-' cleanly expel the entire contents of the tube, with advantageous economy in the use of a paste or cream. 1

The improved device is particularly intended for use with tubes containing dental. and shaving pastes or creams and the like, but it will be understood'that it may serve with equal efficiency in expelling from collapsible tubes other paste or cream-like material, such as surgical dressings, ointments, oils, paints or any other similar material.

The invention consists in the preferred construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawing:

Fig. 1 is a perspective view of the improved attachment shown as attached to a shelf or ledge, a collapsible tube being indicated in dotted lines as associated therewith;

in dotted lines, compressed and rolled and held within the improved attachment.

The numeral 5 designates a fiat plate of suitable metal having more or less inher-. ent resiliency and provided with a supporting tongue 6 having a lower curved extremity or posite side holding arms 8 having lower curved ends 9, the ends 9 being bent in a direction reverse to the lower curved extremity of the supporting tongue 6. The arms 8 are formed by cutting the metal plate 5 in directions diverging towards the lower end of the plate, the slots thus produced having a regular divergent formation, as at 10, and then merging into, or continuous with, longitudinally straight slots 11, the straight slots being parallel with the sides of the plate 5.

Inserted between the arms 8 and the lower curved extremity or end 7 of the tongue 6 is a tubular key 12, the bent or rearwardly curved ends 9 of the arms 8 frictionally bearing on the outer portion of the key at opposite edges of the lower curved end of the tongue. The key 12 is preferably constructed from a single piece of material, shaped to provide a tubular body 13 having a slot or inlet 14 extending .the full length thereof, one enduof the key being. flattened and extended outwardly to produce a gripping-terminal or handle '15, by means .Of which the key as a whole may be readily rotated in a manner which will be more fully hereinafter explained. The plate 5 16 therein to receive suitable fastenings; for attaching the same to a ledge or other'si'i-pport 17, as shown by Fig. 1.

In the/operation of the improved device closed end of the collapsible tube is inserted inthe slot 1 1 of the key' 12 and the latter rotated towards the tongue 6,

' tened extremity of the tube on the key and quantity desired and in accordance with the' rotation of the key. As the tube is wound upon the key 12 and the diameter of the collapsed and wound portion of the tube inend 7 and also provided with o'pthereby Winding the lower flatcreases on the he 12, the lower ends of the arms 8 and the ower curved extremity of the tongue 6 which always exert a yielding pressure on the wound and collapsed portion of the tube, are correspondingly separated. When it is desired to replace an the key 12 may Q-a' collapsible tube.

empty tube by a filled one, be rotated in the opposite direction to artly unwind and release the wound portion of the tube therefrom, but without unwinding the full length of the tube, it being only necessary to turn the key 12 in an unwinding direction for a half or full turn, to permit the 'ke to be withdrawn, thus releasin the arti ly unwound tube from the ho der. he key is then replaced in the holder and a full tube applied thereto. The improved.

device is ve simple, in construction and o ration add will be found exceptionally e ective @in performing the function for which it has been devised, It is obvious that changes in the proportions, dimensions and minor details. of construction may be adopted without departing from the spirit of the invention, and it is also proposed to ornament the im roved device in any suitable manner, as platin or general design work, and t e speci c configuration L, thereof as shown in the drawings may: be varied. While it is preferred that'the im-' proved attachmentbe applied to a shelf or the like as shown and heretofore described, it may be used in any other position desired. The'improved holder may also be used without attaching it to a support.

What is claimed as new is: 1. A device, of the class specified, comprising a plate having a tongue and a plurality of arms forme integrally therewith and extending thereform, said tongue and arms having their extremities free and said arms being bent away from said tongue aeeaaei adjacent their connection with said plate, said tongue having its free end bent toward said arms\and said arms having their free extremities bent toward said tongue, and a key rotatable between the extremity ofsaid tongue and the extremities of said arms, said key having means to engage one end of 2. A device of "the class specified comprising a plate, a ton e of resilient material carried by one e ge of said plate and a pair of arms also of resilient material carried by said edge of said plate one at either side of said tongue, said tongue and arms having their opposite extremities free and the extremity of said tongue being bent toward said arms and the free extremities of said arms being bent toward said tongue,

anda key mounted to rotate between the bent extremities of said tongue and arms and provided with means to engage one end of a collapsible tube.

3. A device. of the class specified comprising a plate having a pair of cuts extending from a point between the ends of said plate to one end of the plate and di-. verging toward said latter edge to form an intermediate tongue and an arm at each side of said tongue, said tongue having its form a support for the end of a collapsible tube and the extremities of said arms being bent toward said tongue, a key rotatable within the bent extremities of said tongue and said arms and having means to engage one end of a collapsible tube, the tongue and arms being relatively. yieldable as said tube JOHN A.
